AIM: To compare the effectiveness of using a topical cream, Ping On ointment, or Vaseline in the treatment of
temporomandibular joint (TMJ) and masticatory muscle pain, in order to establish the true effi cacy of Ping On ointment.
SUBJECTS AND METHOD: In this randomized, double-blinded, placebo-controlled trial, 55 subjects with TMJ and/or masticatory
pain (Group 1 patients according to the Research Diagnostic Criteria for Temporomandibular Disorder) received Ping On Ointment
for 4 weeks or a placebo for 4 weeks. The subjects were evaluated with standard measures of effi cacy: pain intensity measured by
visual analogue scale and maximal comfortable mandibular opening, at baseline and after 4 weeks of treatment.
RESULTS: Ping On ointment signifi cantly reduced the symptoms of painful TMJs and/or masticatory muscles. Maximal
comfortable mandibular opening also improved signifi cantly with Ping On ointment compared with the placebo, but this was
not clinically signifi cant.
CONCLUSIONS: Topical application of Ping On ointment may be considered to be one of the fi rst line treatment modalities
before prescribing analgesics, for the management of temporomandibular dysfunction (TMD). It is topically applied, with
minimal systemic effect, reversible, economical and effective in managing TMD and masticatory muscle pain.link_to_subscribed_fulltex
